"She hasn't been found yet so I'm not going to give up on her," Lisa Smith said.

She remains strong even though so much has happened in the past week. Kaylie, 21, and 18-month-old Lana were reported missing by Kaylie's grandfather in Olathe on May 3. Kaylie's body was discovered Monday in rural Franklin County and identified on Wednesday.

Police say Lana is presumed dead, but her body has not yet been recovered.
